Static and Dynamic Characteristics of Thermal Sensors
1, the static characteristics of thermal sensors:
The static characteristics of the thermal sensor refer to the static input signal, The relationship between the output of the thermal sensor and the input quantity is interrelated. Because then the amount of inputs and outputs and are independent of time, So the relationship between them. That is, the static characteristics of the thermal sensor can be expressed by an algebraic equation without time variables, Or the amount of input for the abscissa. And the corresponding output, as the ordinate and draw the characteristic curve to describe. Characterization of the main parameters of the static characteristics of the sensor are: linearity, sensitivity, resolution and hysteresis.
2, the dynamic characteristics of thermal sensors:
The so-called dynamic characteristics, Refers to the thermal sensor in the input changes, Its output characteristics. In practical work, The dynamic characteristics of the sensor are often expressed in response to certain standard input signals. This is because the sensor response to the standard input signal is easy to use experimental method. And its response to the standard input signal and its response to any input signal there is a certain relationship between, Often know the former can presume the latter. The most commonly used standard input signal is a step signal and a sinusoidal signal, So the dynamic characteristics of the sensor is also commonly used step response and frequency response to represent.
